bro codechef is good for cheaters only . if u are trying honsetly u will most probably have hard time .
just copy solutions , codechef will look like best place 
. and u can brag everywhere
But in long challenges I think load on server is not high then also same problem was there with one of my friend in April Long Challenge.
